Performance Evidence

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.

There must be evidence that the individual has installed rigging equipment and controlled at least six loads from an aerial location to the drop zone using ropes, knots and rigging system appropriate for the load dimensions and mass.

There must also be evidence that the individual has:

confirmed work instructions and location of worksite

identified site hazards, assessed risks and confirmed controls with supervisor including:

selected, checked and used appropriate personal protective equipment

confirmed the availability of first aid and emergency equipment, personnel and procedures

implemented workplace health, safety, environmental and traffic control measures

contributed to tree assessment process by assessing trees for defects

checked and removed defective equipment from service

monitored rigging system, work team movements and environmental conditions for safe work conditions

communicated with work team and discussed and confirmed rigging method and rigging equipment during operations using agreed communications methods

tied, dressed, set and finished arborist knots according to rigging task, including demonstrating the following knots:

alpine butterfly knot

bowline on the bight

cow hitch with better half

clove hitch and two half hitches

half hitch pre-knot

klemheist friction knot

marline pre-knot

marline spike hitch

riggers knot and two half hitches

running bowline

sheet bend

slippery sheet bend

timber hitch

zeppelin bend

controlled load to drop zone, adjusting rigging according to aerial worker instructions and disconnected load from rigging system

returned rigging components to aerial work team after checking components for defects

confirmed completion of rigging operation with aerial work team and removed and dismantled rigging system including:

cleaned, checked and stored tools and equipment from worksite

reported and tagged defective tools and equipment

recorded and reported rigging outcomes according to workplace procedures.

All ground-based tree rigging work is required to be performed according to preferred industry practices (as outlined in the Companion Volume).
